Din 16742: - Tg5 Fixed

Dimensions formed by a single mold part (tool-fixed) generally achieve higher accuracy than those formed by moving tool parts or across parting lines (non-mold-fixed).

The standard (now largely superseded by DIN ISO 20457 ) defines tolerances for plastic molded parts. Specifically, TG5 represents a "Tight" or "Accurate Production" tolerance group, typically applied to high-precision engineering materials like Polyamide (PA). din 16742 - tg5

To avoid confusion, use this exact notation on your technical drawing: Dimensions formed by a single mold part (tool-fixed)

By understanding the rigorous demands of DIN 16742 - TG5, you can communicate effectively with molders, control manufacturing costs, and deliver plastic components that perform flawlessly in the real world. Remember: In the language of plastic tolerances, TG5 speaks the dialect of uncompromising precision. To avoid confusion, use this exact notation on

Achieving TG5 tolerances often requires increased cooling time, higher-quality tooling, and tighter environmental controls in the production facility. 4. Implementation Guidelines

(TG6 is finer than TG5, offered only by specialized molders)
